Unasked, but note that a CPU with more MIPS may be slower than another different CPU with less MIPS. MIPS just counts instrctions per second. Now how much useful work can be done per instruction.

FLOPS is widely used by people who want to simulate something. NASA uses CELL (it uses FLOPS) to simulate how does sun, planet and universe works, you might not want to use MIPS on that since it may take forever to generate the results from it. Also the high-end GPU now a days uses a FLOPS as their instruction code, since it uses geometry to generate graphics which is FLOPS is indeed a good use for GPU.

Other end is MIPS which is widely used in PC and MACS today. MIPS based processor are used because it's cheap to produce and easy to code a programs on it.

They're not types of processor. (Well, confusingly, MIPS is, but it's not what you're talking about, and it's not used in PCs.) They're both types of measurement. MIPS measures instructions per second. FLOPS measures floating point operations per second.
